132-xxSM Series

Maxi Spring™ Air Core Inductors

RoHS compliant AEC-Q flag
Our 132-xxSM Series Maxi Spring™ air core inductors have exceptionaly high Q factors and very tight inductance tolerances, making them suitable for narrowband RF amplifier matching and tuning applications. As their name implies, air core inductors do not use a magnetic core, resulting in high Q and the lowest possible losses for high-frequency applications. High-reliability versions are available for space, military, and other critical applications.
  • Inductance values from 90 nH to 538 nH
  • Exceptionally high Q even at low frequencies
  • Handle up to 3.5 Amps current
  • Tight tolerance (as low as ±2%) can eliminate circuit tuning
  • Flat top case for mechanical stability and reliable pick and place operations
  • Solder coated leads ensure reliable soldering
  • AEC-Q200 Grade 1 (−40°C to +125°C)

Notes
  1. When ordering, please specify tolerance, termination and packaging codes: e.g. 132-20SMJLD
  2. Inductance and Q tested at 50 MHz on an Agilent/HP 4291A with a 16193 fixture and correlation.
  3. Tolerances in bold are stocked for immediate shipment.
  4. SRF tested on the Agilent/HP 8753D and a Coilcraft CCF1248 test fixture.
  5. DCR tested on the Cambridge Technology Model 510 Micro Ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  6. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Tolerance:

  • = 2%, = 5% (Table above shows stock tolerances in bold.)

Termination:

  • L = RoHS compliant tin-silver (96.5/3.5) over copper.
  • T = RoHS tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost)
  • S = non-RoHS tin-lead (63/37) over copper. (Special order, added cost)

Packaging:

  • D = 13″ machine-ready reel.
    EIA-481 embossed plastic tape, 800 parts per full reel. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel.
    In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
